Under the uncertainty of risk characterization, the downward risks brought about by climate change may have an amplification effect on risks, profoundly affecting social economy, culture, and life. The complexity of climate risk indicates that traditional climate communication models are no longer able to adapt to the requirements of overall social change, and innovation in climate communication needs to be achieved through the overall logic of mutual construction and collaboration. This study starts from the era background of climate emergency and a community with a shared future for mankind, and combines the theoretical perspectives of uncertainty, ecological philosophy, and systemic risk to examine and consider the potential characteristics and internal mechanisms of climate communication. It is believed that the synergistic effects of multiple systems such as climate communication reception, spillover, and feedback should be integrated to improve the understanding of the interaction between climate risks, and further explore the future of climate communication in terms of conceptual innovation and feedback from a practical perspective The possible paths for improving the four dimensions of port forward movement, subject collaboration, and content optimization are aimed at achieving a shift in the reality of climate communication.
